United States Patent O 3,011,672 GLUED CELL FGRMING DIVIDER Joseph Vesak, Richmond, British Columbia, Canada, assignor to Crown Zellerbach Canada Limited, a corporation of Canada Filed May 28, 1958, Ser. No. 738,563 2 Claims. (Cl. 217-30) The invention relates to a collapsible strip type cellular partitioning and compartment forming device for corrugated and solid libreboard containers which devides the container into a plurality of substantially similar shaped cells for packaging and shipping fragile articles such as beverages packed in glass containers and the like.

More speciiically the present invention pertains to a strip or web type cellular partitioning means comprising a plurality of interconnected planar or plate-like partition forming webs, preferably of equal height, arranged in their collapsed state, in partially odset face to face contacting relation, each web being divided by equally spaced apart longitudinal parallel lines of Weakness into relatively narrow and reratively wide portions. The said webs are secured together by adhesive applied to alternate narroaJ portions of each web and the longitudinal side margins of each web have tab dening lines of weakness. The partition may be secured to the interior faces of the walls of a slotted carton by glue applied to said tabs on the side margins of each web or to the interior faces of a liner adapted to be dropped, with the partition device attached, into the container, the partitioning means when the container is erected, dividing the container or the liner therefor into a predetermined number of similar shaped cells.

An object of the invention is to provide a strongdurable strip type partitioning means comprising at least two plate-like partition forming members each divided by parallel longitudinal scores into relatively Wide and relatively narrow portions, the strip like members being interconnected by adhesive applied to alternate relatively narrow portions of each strip. The partition may be shipped in collapsed form and readily opened into cell forming position at the point of use.

Another object is to provide a. partition and compartment forming device which comprises interconnected entire and planar or plate-like partition forming members, preferably of equal height, positioned in flatwise partialiy offset contacting relation inthe collapsed form and which may be moved from the collapsed position to the erected position wherein said interconnected members become positioned at right angular cell forming relation to each other.

Another object of the invention is to provide a collapsed strip type partition and compartment forming device secured to the inner walls of a regular slotted container or a liner for the container, the device consisting of not less than two strips or webs of paperboard in flatwise partially overlapping relationship, each of said strips being divided into equally spaced apart relatively wide planar portions and relatively narrow portions by pairs of longitudinal parallel lines of weakness, with tabs on the side margins of said strips. The strips are secured together by glue or other means applied to alternating relatively narrow portions of each of said webs and to the inner face of the container or drop in liner by glue or other means applied to said tabs.

The invention comprises a collapsible partition compartment forming device formed of a plurality of platelike strips or webs of equal height arranged in face contasting relation divided by longitudinal parallel lines of Weakness into relatively wide partition forming portions of one of said strips being secured by adhesives or other suitable means to like portions of alternating strips. whereby, in the operating position of said partition, the relatively wide portions thereof become positioned at right angles to each other and the relatively narrow por.- tions diagonally disposed to said Wide portion.

The glued cell forming divider or partition in opened up cell forming position attached to the inner face of the walls of a slotted carton is shown in perspective in FIG. 9, while the divider or partition device attached to the inner faces of a liners walls adapted to be dropped into a regular slotted carton is illustrated in FIG. l0.

The novel divider or partition is formed by transversely severing a continuous face to face assembly of counterpart pairs of face to face strips or webs of varying Widths arranged in partially oiset relation as shown in the plan view of FIG. 3 of the drawings and the side elevation of FIG. 4.

A schematic view of one means of forming the partition is illustrated in FIG. 1 wherein pairs of counterpart webs A and A-1, B and B-1, C and C-l, D and 1)-1 are drawn from rotary, spaced supply rolls 1 to 8 inclusive. The webs pass from the supply rolls through suitable scoring rolls 30, glue fonts 1t) and tension rolls 11, intoV a relatively long pressure section 12, where the alternating adjacent webs are permanently adhesively secured together at the equally spaced relatively narrow longitudin portions 25 hereinbefore described. After the pressure section, the webs are allowed to accumulate slack before passing through an intermittent rotary feeding means 13 to a knife 14 where the webs are severed transversely at spaced intervals equal to the desired cell height, forming the completed collapsed partitions 16.

FIG. 2 is a schematic illustration of a method which may be employed for assembling the cartons 17 and the completed partitions 16. The cartons 17 are fed from a carton storage facility 18 through an adhesive application cylinder 19 where adhesive is applied to the blank. Glue font 2li applies adhesive to the cylinder 19.

The carton is then passed under a partition storage facility 18:1 from which a collapsed partition is deposited on the glued carton blank in proper registering relation. The carton blank 17 is then folded to form the assembled container 21 in knocked down at form, the assembled container 21 then goes through a suitable squeeze roll section 22, thence to a bundling station.

The partition device may consist of one pair of said juxtaposed partially offset webs for forming a four cell partition, such Vas for example, the A and A-l strips, or a plurality of counterpart pairs of webs.

In the embodiment of the invention illustrated in the drawings, eight counterpart strips or webs are employed which forms a twenty-four cell partition for attaching in collapsed form to the walls of a container.

Each of the webs are divided into relatively wide portions 24 and relatively narrow portions 25 Iby parallel equally spaced apart scores or other forms of lines of weakness, 29. Each of the webs also have marginal gluing tabs 23 deined by lines of weakness for securing in right angular relation to the inner faces of the con tainer or liner. As best shown in FIGS. 3 and 4, the eight webs increase in width from web A to web D and from web A-l to web D-l. The web A is located at the top'andvA-1 at the bottom of the assembly, each web oiset laterally by the Width of a major portion 24 dened by the parallel scores and with the parallel scores in vertical alignment.

Prior to the assembly of the Webs glue is placed on the relatively narrow portions 25 and then pressure applied Y to the assembly to secure the strips in the position relative to each other as shown in FIGS. 3 and 4. It should be understood that the fragmentary illustration of FIG. 3 shows the mannery of assembling the eight counterpart webs in a continuous operation. The continuous assembly of the counterpart pairs of webs is transversely severed at spaced intervals corresponding to the desired height of the partitions.V The collapsed partition thus formed may be positioned and secured to the walls of a container blank as illustrated in the progressive folding of the container blank and collapsed partition positioned thereon with glue, 26 on the right angularly folded tabs 23 (FIGS. Sand 6) to the completely collapsed form shown in FIG. 7 ready for shipment. Perspective views 9 and 10 show the container and liner respectively opened into rectangular form with the partition forming twentyfour rectangularly shaped cells, secured to the inner face of the walls. v

The inter-relation of the severed webs of the assembly is shown inV the perspective drawing FIG. 8 at certain .stages of the erection or collapsing of the container. It

will be noted that the relatively -narrow portions of each n of the Webs 25 to which the glue 26 Vis applied are in parallel relation to each other and in diagonal relation to the relatively large portions 24 of the Webs which form the Vvertical planar, entire walls of the partition. This same diagonal relationship of the narrow portions 25 to the right angular portions 24 is also shown in FIGS. 9 and l0.

The hereinbefore described collapsed container having integral partitions has several important advantages. First of all it is simple and inexpensive and may be shipped and stored in preassembled condition collapsed form. Furthermore, economies are realized through the speed of manufacture and eliminates the need of the usual labor employed to hand position partitions into containers.

While I have shown and described a twenty-four cell partition, partitions may be made with varying numbers of. cells. For instance, a simple four cell vcarton could be made from two webs like the upper and bottom webs A and A-1 shown hereinbefore. Y

Obviously, the hereinbefore described carton and partition members may be embodied in other forms and the above is illustrative only and not restrictive,
